Definitions
- the present invention addresses an apparatus and a method for wet scrubbing of pollutants in air and flue gases.
- Wet scrubbing apparatuses are known for removing particulates from flue gases and air.
- the object of the present invention is to obviate, at least partially, the drawbacks of prior art and particularly, the above mentioned drawbacks.
- FIG. 1 is a longitudinal sectional view of the apparatus
- FIG. 1 is a side view of the apparatus
- FIG. 3 is a side view of a detail of the apparatus
- - Figure 4 is a side view of another detail of the apparatus;
- - Figure 5 is a first cross sectional view of the apparatus;
- FIG. 7 is a side sectional view of an alternative embodiment of the apparatus.
- the wet scrubbing apparatus comprises a central chamber 1, which extends in a substantially and/or generally vertical direction, and has an inlet 2 at its bottom for the gas and/or flue gases to be purified.
- the central chamber 1 is surrounded by a plurality of chambers 3, 4 in a substantially concentric arrangement around the central chamber 1.
- the central chamber 1 and the concentric chambers 3, 4 are connected in series and the outermost concentric chamber 4 has one or more outlets 5.
- the central chamber 1 and the concentric chambers 3, 4 are formed by a plurality of elements 13, 14, 15 having a tubular shape or other with square or round section shapes.
- tubular elements 13, 14, 15 are made of steel, more preferably of stainless steel.
- Suitable air delivery means 6 are provided, typically an adjustable-speed fan, situated upstream or downstream from the central chamber 1 or inside it to generate a current of air and/or flue gases that sequentially travels from the central chamber 1 to the concentric chambers 3, 4.
- each chamber 3, 4 has a generally annular manifold 27 which has the nozzles 7 connected thereto.
- Valves may be further provided for separately adjusting the flow rate of the water sprayed
- the droplets of water sprayed into the concentric chambers 3, 4 retain the particulates contained in air or in the flue gases which travel through the concentric chambers 3, 4 and fall into a water collection tank 9.
- the water collected in the tank 9, after being filtered, is delivered again to the nozzles 7.
- the collection tank 9 may be equipped with a drain valve (see Fig. 4) for draining the tank when needed.
- the gas and/or flue gas stream flowing up through the central chamber 1, repeatedly flows up and down through the concentric chambers 3, 4 and is alternately subjected to a wash and backwash action.
- a mechanical filter 11, for instance a layer of nonwoven fabric may be provided at the outlet 5 of the wet scrubber apparatus to retain the residual particulates from the washing process.
- At least one perforated plate 12 or wire gauze 10 is provided in each concentric chamber 3, 4.
- wire gauzes 10 have a mesh of not less than lxl mm and not more than 10x10 mm.
- the mesh of the wire gauze 10 is dependent on the relevant application of the system and on the pollutant to be treated.
- the gauzes 10 may be mounted in closely spaced pairs, one above the other.
- perforated plates 12 are mounted in closely spaced pairs, otherwise gauzes 10 are provided in pairs with perforated plates 12.
- the central chamber 1 and the concentric chambers 3, 4 have increasing sections, whereby the gas stream has a decreasing speed as it passes from one chamber to the other.
- the particulates collected in the tank 9 tend to form a slurry which prevents proper operation of the apparatus.
- the water collected in the tank 9 is transferred to an underlying filtering tank 32, for removal of the suspended particles therefrom.
- the filtered water is pumped to the nozzles 7 by a pump 8.
- the filtering tank 32 includes a plurality of mechanical filters 33, 34, 35, 36 having an increasing filtering degrees, which are arranged in series.
- the first filter 33 may have a filtering degree, as needed, of 250 ⁇ m to about
- the water level in the filtering tank 32 is adjusted by a valve 20, which is driven by a level switch 21.
- a manually or electrically operated drain valve 22 is further provided to drain the filtering tank 32 when needed.
- the fan 6 is situated downstream from the scrubber apparatus (Fig. 6), i.e. at or near the outlet 5 of the outermost concentric chamber 4.
- the above described apparatus can be adapted to a variety of needs, particularly for purifying gases from civil or industrial heating boilers, conditioning systems downstream from air intakes, carpenter shops, mechanical or metal and mechanical shops, etc.
- the apparatus is mounted on a special metal frame 30 and has a switchboard 31 which includes a thermomagnetic safety device and a speed control for the fan 6.
- the electric panel 31 further includes an audible and visual alarm system, for signaling any failure in the electric and drive system or water missing conditions in the tank 9.
